Compute the slope of the line passing through the points (−5,7)(−5, 7) and (−2,−2)(−2, −2).
You are given the point (−1, 2) and a slope of −32{\(\displaystyle\]\displaystyle\)}-\(\frac\)32. Which of the following points will also lie on the line if you apply the rise and run from the given point? (Select the single correct point.)
Which of the following descriptions correctly identifies the slope of a vertical line and explains why?
Two roads on a small map are modeled by lines: Road A goes through (0,0) and (4,6); Road B goes through (0,0) and (3,5). A city planner asks which road is steeper and by what factor is the steepness greater? Compute and justify.
A wheelchair ramp must rise 2 feet for every 12 feet horizontally to meet a building entrance. Starting from ground-level point (0,0), write the slope and find the coordinates of the point at the top of a 36-foot section of ramp, then state the slope-intercept equation of the ramp line.
